PULPING-MACHINE.

' Specification of Letters Patent.

Application filed February 1, 1917. Serial No. 145,875.

means are provided for breaking up the fruit as it is fed into the perforated screen, thereby making the product uniform and preventing injury to the screen.

A further object of my invention is to provide improved mechanism having a safety device for preventing foreign substances from getting into the screen.

A further object of my invention is to provide an improved machine in which the feeding and crushing mechanism is readily accessible for cleaning and repair.

A further object of my invention is to providean improved pulp machine in which the drier pulp is uniformly mixed with-the juicier pulp to insure a uniform product.

In the drawings,'in which one embodiment of my invention is shown:

Figure 1 is a vertical longitudinal section v of a pulp machine embodying my invention.

Fig. 2 is an elevation of the supply end of the pulp machine.

Fig. 3 is a sectional view on the line 33 of Fig. 1.

Fig. 4 is a sectional view on the line 44 of Fig. 1.

Fig. 5 is an enlarged sectional view of the feed worm and driving connection.

Fig. 6 is a perspective view of the feed worm casing.

lteferring now to the drawings in detail, the pulp machine comprises an elongated cylindrical headed apertured receptacle 10, a rotary stirrer or agitator 11 for forcing the fruit through the apertures in the receptacle a drain pan 12 which receives the material forced through the apertures in the receptacle 10; an outlet 13 for the discharge of the material which is not forced through the apertures in the receptacle, mechanism 14 for feeding the fruit to the receptacle 10 and breaking it up, driving mechanism 15 for the agitator 11 and feed mechanism 14 and a frame 16 for supporting the receptaclelO, driving mechanism 15, etc.

The receptacle 10 comprises a lower semicylindrical apertured screen 17 and a semicylindrical hood 17 which can be removed to permit access to the interior of the receptacle, a feed head 18at one end of the receptacle 10 and a discharge head 19 at the other end of the receptacle.

The agitator 11 comprises a plurality of. paddles 20 secured to rotatable spiders 21.

The drain pan 12 extends beneath the receptacle and is provided with an outlet 22 and is hinged at one side to the frame 16 at 23 and latched to the other side of the frame at 24. I

The feed mechanism 14 comprises a worm or screw 25 rotatably mounted in a casing 26, through the apertures 27 of which the Patented Apr. 29 1918.

fruit is forced into the receptacle 10; the

inner end of the casing 26 may be provided with radial ribs 27 -to prevent the fruit from slipping along the end of the casing. The fruit is supplied to the feed mechanismby means of a hopper 28.

The driving mechanism 15 comprises a shaft 29 to. which the spiders 21 and worm 25 are secured, mounted in suitable bearings 30 and 31 at the end of the frame 16; a pulley 32 drivenfrom any suitable source of power not shown and any suitable clutch member 33 for connecting and disconnecting the shaft 29 with respect to the'pulley 32.

The screen 17 has its end edges permanently secured to the heads 18 and 19 and its side edges fixedly secured to the side member 34 of the frame. The hood 17 is detachably secured in position by means of the eccentric clamps 35 which force the sealing strips 36 into engagement with the laterally extending flanges 37 of the screen 17. p

vided between the shaft 29 and the worm 25.

This shear-pin connection comprises-a colmade separate from the frame 16, so that q tuned receptacle, means for supp ad acent one end of said receptacle; an ag1- by detaching the bracket 48 from the frame 16 and slipping it off the end of the shaft 29,

the outer portion 47 of the hopper, together with the worm 25, may be slipped off the end of the shaft for cleaning, repairing, etc.

The side members 34 are secured at their ends to front and rear supporting members 49, 50, respectively, as indicated in Figs.

1 and 2.

The outlet 22 of the drain pan is nearer the discharge head of the pulper. The slope of the drain pan from the discharge end to the outlet 22 is considerably steeper than the slopefrom thefeed end. The reason for this is that the material forced through the screen 17' is juiciest at the feed end and driest at the discharge end and the juicier material runs much more freely than the drier material, the juicier material requiring a lesser slope to cause it to flow toward the outlet. As a result of these difl'erent slopes of the drain pan, the juicier material is uniformly mixed with the drier material and the result is 'a uniform product.
